Resin-Bonded Inlay Retainer Prostheses for Posterior Teeth. A 5-Year Clinical Study

This study evaluated posterior resin-bonded prostheses using inlays as retainers. Thirty-nine patients missing at least one premolar or first molar received 51 resin bonded fixed partial dentures with high noble alloy inlay retainers and a metal ceramic pontic. Resin luting material bonding to the framework was secured by the Silicoating method (24 fixed partial dentures), lost sugar method (13 fixed partial dentures), or tin plating (14 fixed partial dentures). Clinical examinations were performed 1 week, 1 month, 6 months, 1 year, 2 years and 5 years after cementation. None of the fixed partial dentures with silicoating or sugar crystal impressions lost retention, whereas two of the tin-plated fixed partial dentures required replacement. Resin-bonded inlay-retained prostheses appear to be a faborable alternative to other type of fixed partial dentures.
